Nodejs: how to clone an object

Question

If I clone an array, I use cloneArr = arr.slice()

I want to know how to clone an object in nodejs.

Answer 1

For a shallow copy, I like to use the reduce pattern (usually in a module or such), like so:

var newObject = Object.keys(original).reduce(function (obj, item) {
    obj[item] = original[item];
    return obj;
},{});

Here's a jsperf for a couple of the options: http://jsperf.com/shallow-copying
